ATTACHMENT TO MILLS FOR PREPARING CORN IN THE COB FOR GRINDING.

Specification of Letters Patent No. 7,386, dated May 21, 1850.

To all whom it may concern:

Be it known that we, JOHN M. SEELY and WM. E. TOMLINSON, both of Lockport, Warren county, Ohio, have invented new and useful Improvements in Corn-Preparers, or

machinery for preparing corn in ear or corncobs for grinding; and we do hereby declare the following to be a full, clear, and exact description of the same, reference be ing had to the annexed drawings, making part of this specification, in which drawings- Figure 1 is an isometric and partly sec tional view of the tubular feeder. Fig. 2 is an isometric view of the cutters and the blocks to which they are attached and Fig. 3 is an isometric view of this block with the outer casing of the cutter-throats and of the recess in the bottom face of the cutter block removed. V

The nature of our invention consists in attaching a cylindrical block or bush by a recess or other device to the balance rim in the eye of the runner ofa pair of burr or other mill stones, the said block having inclined faces leading to throats opening beneath knives adjustedthereto, and the said throats winding around the periphery of the block and delivering themselves into the eye of the runner, so that ears of corn thrust into tubes of a size suitable therefor in the body of a feeder or cap will come in contact with the rotated knives and be minutely cut up, and fed to the mill stones, the said tubular feeder or cap being either appropriately held or made stationary for that purpose and the tubes therein being at a dist-ance apart equal to that of the diametric distance of the knives apart.

In Figure 1 in the drawings annexed, (a) is the body of the feeder (b) handles or projections therefrom for holding it or making it fast, a is the feeding tube in the cap (d) is a section of a similar tube each feeder or cap having at least two.

In Figs. 2 and 3, (e) is the body of the block or bush of which the upper portion (f) is made of larger diameter-among other reasons for the purpose of furnishing rims for external sides of the inclined planes (g) which lead to the radial entrance of the throat The knives (it) have their cutting edges, set radially and immediately over the throat (i) which wind spirally to the extent of the fourth of circle around and down the periphery of the block (6) and are sheathed on their outer sides by casings (j) which when in place are so shaped as to be flush with the periphery of the cylinder and the bottom face (Z) of the port-ion (f). (72) is a recess in the bottom face of the block (6) by means of which or any other suitable device, the block is attached to theirons driving the runner.

We thus attain by a simple and efficient arrangement a mechanical concentration of parts suitable for feeding and cutting up corn in the ear, or corn cobs as called by some, and performing this latter operation 1n the very eye of the runner stone of a grinding mill, s that the chopped or shaved stuff is at once conveyed to the grinding surfaces of the, stones, the whole combination of operations being thus economically compactly and rapidly executed.

The cobs being held down onto the top of the block by suitable pressure, descend successively the incline planes (g) and intercept the knives which slice off as much as is due to the descent of the inclines, and the receding direction given to the throats cooperates with the motion of the runner, in facilitating the discharge of the particles.

Having thus fully clearly and exactly described the nature, construction and operation of our invention, what we claim as new and desire to secure by Letters Patent is- 1. The block (e) with its arrangement of incline planes, knives, throat, and other devices, which adapt it to operate on corn cobs or ears of corn received from a suitable feeder, and also to be inserted in the eye and be driven by the irons of the runner stone of grinding mills, substantially in the manner and for the purpose described.

2. Ive also claim the block (6) arranged as described in combination with the tubular feeder, arranged substantially in the manner represented in Fig. 1 and for the purpose described.
